Hi, this is Don from Zaber Technologies.
Your timing is good, because I just spent the last few days writing a new set of labview demos for controlling our devices. The demo now lets you enter a list of commands, and it will execute each command and wait for a response before sending the next command.
As for adding a delay after each command, here are three options:
Leave the new demo as is. It waits for a response and then immediately sends the next command.
Add a delay after each command, but make it the same delay every time. To do that, add a sequence frame inside the inner loop of the demo with all the current code in the first step and a timer in the second step. Wire a constant to the timer.
Add a custom delay after each command. Do the same things as for the previous option, but also add a delay field to the request cluster. Then you'd have to unbundle the cluster inside the loop, rebundle the pieces that the MakeRequest subvi needs, and pass the delay to the timer in the second step of the sequence. Hopefully you don't need to go that far.
I'm still working on the new demo, so it's not published yet. I'll send you the work in progress, and I'll publish it here when it's done:

I'll probably link to a separate Labview tutorial page from there. If anybody is looking for it in future and can't find it, just ask at our contact page:
